5.1.1 CapTIvate Module and GUI Function Description

The CapTIvate module consists of a Block and a CapTIvate Core. The Block is responsible for scanning the external capacitance. The CapTIvate Core is responsible for the scanning control of the block and the anti-noise function. One Block corresponds to four CAP I/O pins. This means that only one CAP I/O at a time can be scanned in each block, so optimal configuration of the button scanning sequence can save a certain amount of time.

In the CapTIvate GUI, the MCU widget and sensor widget are used to configure the CapTIvate module. The relationship between the GUI andthe CapTIvate module is shown in Figure 5-2. The sensor widget is mainly responsible for the control of the Block. The MCU widget is mainly responsible for the control of the CapTIvate Core.
